  1. 11. An Analysis of C14 for SNO+
    Victoria Howard (SNOLAB)
    23/08/2021, 14:00
    Physics Analysis

    SNO+ is a liquid organic scintillator detector aiming to study neutrinos, which is now completely full of scintillator with the addition of wavelength shifter addition ongoing.
    C14 is a background within the SNO+ detector that has been measured to yield a beta decay rate of 0.8 Hz/m^3 and 1.3 Hz/m^3 from simulation. This makes it a uniform, high rate and dependable source within the acrylic...

  2. 19. Analyzing Neck Events in the SNO+ Experiment
    Mr Kai Soini (SNO+ - Queen's University)
    23/08/2021, 14:15
    Physics Analysis

    The SNO+ experiment is located in Sudbury, Ontario, 2km underground to shield it from cosmic radiation in search for neutrinos - the ghost particle. Using the 780 tonnes of liquid scintillator, primarily Linear Alkylbenzene (LAB) that make up the SNO+ active volume, we observe different types of events in the detector, so detecting neutrinos requires very careful data selection to avoid...

  3. 17. NEWS-G3 Muon Background Simulation
    Clara Mitchinson (Queen's University)
    23/08/2021, 14:30
    Physics Analysis

    NEWS-G searches for dark matter using spherical proportional counters (SPCs), which are large, gas-filled metal spheres with a small sensor at the centre held at high voltage. SPCs are used to detect the interaction of particles (such as dark matter or neutrinos) in the gas by measuring the charge induced on the sensor due to amplification of the primary ionization near the sensor. The NEWS-G3...

  4. 18. Feature Recognition and labelling for Photogrammetry Calibration of the Super-Kamiokande Detector
    Tapendra B C

    Physics Analysis

    The Super-Kamiokande detector is a 40m tall cylindrical tank with a 40m diameter, filled with ultrapure water. It makes detailed measurements of solar, atmospheric, and accelerator neutrinos. About 11,000 PMTs (photomultiplier tubes) facing inwards are set up on the detector wall to record neutrino interaction events. The use of the accurate location of photomultiplier tubes (PMTs) on the...

  5. 16. PICO 500 Muon Veto Optical Calibration System
    Laurie Amen (Queen's University)
    23/08/2021, 15:00
    Instrumentation/Hardware

    The PICO 500 detector will continue the search for one of the leading dark matter candidates: the WIMP. Even under 6800 feet of rock shielding at SNOLAB, the PICO 500 bubble chamber is still exposed to a background of cosmic muons. The resulting interactions within the chamber’s active fluid are very difficult to discern from the extremely rare WIMP-nucleon interactions that the experiment...
